Back packing must! - Katadyn Hiker Pro Transparent Filter

Went on my first 3-day back packing trip. Did a lot of research and found Katadyn Hiker Pro was the best bang for the buck. It worked well without any issues. Make sure to follow the instruction and clean it after every use. I was porting about 2 liter per stop and it worked like a charm. The water tasted clean and I did not get sick! I highly recommend this product for it's value and ease of use.
